【Character】

The appearance of  Macro-pored micro-spherical silica gel is white transparent or translucent. It has uniform microporous structure, stable physical and chemical properties, good thermal stability and high mechanical strength. The average pore size is 8.0-12.0 nm, the specific heat is 0.92 kJ/kg C, and the thermal conductivity is 0.167 kJ/mhr C.

【Application】

This product is used as catalyst and catalyst carrier in the important industrial production of melamine, aniline, o-toluidine, vinyl acetate, phthalic anhydride, maleic anhydride, butadiene rubber, acrylonitrile, etc. It is also widely used in the refinement and removal of aromatic hydrocarbons from petrochemical products. It can also be used in pharmaceutical purification, selective adsorption separation of organic gases and liquids, and ion exchange for the removal of polyvalent harmful elements in water.
